llVlPROVEMENT IN THE MANUFACTURE OF HYDR OCARBON OILS.

Specification forming partof Letters Patent No. 3E,5, dated arch 26, 1861.

"0 (LZZ whom it may concern:

Be it known that I, LUTHER ATWOOD, of the city and county and State of New York, have invented certain new and useful Improvements in the Manufacture of Hydrocarbon Oils; and I hereby declare that the following is a full and correct description thereof, ref

erence being had. to the drawing annexed, making a part of this specification, and to the letters of reference thereon.

My said invention relates to the condensation of the liquid products of substaneesdistilled in the manufacture of hydrocarbon oils. By the present modes of condensation the greater part of the higher boiling-point products are saved, and also a considerable portion of the more volatile products; but notwithstanding the use of the best surface-condensers, and condensers surrounded with cool water, and further washing the escaping gases by showers of cold water, a considerable portion of oil-vapors pass off mechanically with the non-condensable products, and a portion of very low boiling-point products also escape, even when the temperature of the escaping gases is as low as 60 Fahrenheit.

My said invention consists insubjeeting these vapors and gases to the direct action of ice, or mixed ice and salt, placed in any suitable vessel connected with the condensing apparatus, and so arranged that the vapors, in passing through it from the condensing apparatus, come directly in contact with ice or ice and salt; and in connection therewith my invention further consists in passing the vapors and gases through the ice-chamber in a descending cur rent, in contradistinction to an ascending current, whereby the vapors are more thoroughly distributed and brought in contact with the ice in the ice-chamber; but more particularly to describe my invention I will refer to the annexed drawing, which represents a vertical cut section of the apparatus.

Letter A represents a double-walled chamber in which ice or ice and salt is placed in lumps of convenient size, resting on the perforated plate or grating 13. The space a betweenthe walls may be packed with sawdust or other suitable non-conducting substance.

0 is aman-hole and plate, through which the ice is introduced. It is secured and luted in any convenient manner.

D is the induction-pipe, provided with a stopcock, and shown broken off, but is to be connected with the escape-pipe of the condensing appartus of a hydrocarbon-oil still or bench of retorts.

Letter E is the eductioirpipe, which leads from the chamber F below the ice-chamber up through the ice-chamber and cover. It is shown broken off, but may be connected with the furnace of a boiler, and is furnished with r a stop-cock, to prevent the back flow of the gas, if so connected, when the manhole is opened to receive the supply of ice.

Letter G is a sealed siphon-overflow, so arranged as to prevent the accumulating oil and water from sealing the eduction-pipe.

Letter H is a draw-cook connected with the bottom of the chamber F.

The vapors and gases admit-ted through the induction-pipe D pass down through the iceehamber by pressure and in opposition to gravity, and thereby are thoroughly distributed and brought in contact with the surfaces of the lumps of ice or ice and salt, the condensable products dripping down into the chamber F, and the noncondensable products passing up through the eduction-pipe. The chamber 1 should be supplied with water at the 00111- mencement, and at the close of the operation the water and the liquid products may be drawn oif through the draw-cock H. An exhauster may be used to relieve the retorts from the pressure necessary for forcing the vapors through the apparatus.

A gas-h older may be connected with the apparatus for the purpose of receiving accumulating vapors while the ice is being received, or the ice-chamber may be duplicated for that purpose. The gases and vapors may also, if desired, be passed through a succession of iceehambers or chambers filled with ice and salt, as described.

I do not wish to confine myself to any partieular form of construction, so long as the construction is such as to bring the vapors and gases in direct contact with the surfaces of the lumps of ice or ice and salt.
